APTA expands National Ranking
The Board approved the recommendation of the Ranking Committee to expand the National Rankings to include all nine categories in which National Championships were played. Previously, rankings had been determined only for the Men’s and Women’s categories.
The Mid-Summer edition of Off The Wire provided the expanded list of rankings, and details on the ranking procedure used for the 1973-74 season.
